said by scottp99:I don't understand what you're saying. No. AES-128 is NOT considered insecure. Far from it.
If AES-128 is so insecure than AES-256, then why is it approved by the US Air Force as decribed the link I posted?
The best published attacks take the relative security down by 2 bits, or say AES-126. Still not practical to attack, even with a global cluster of supercomputers.
As for standards? It's possible that a military would require far stronger encryption than what is currently strong. They might have an interest in keeping their secrets safe 20, 30, 50 years into the future.
Any claim that the root of a problem is simple should be treated the same as a claim that the root of a problem is Bigfoot. Simplicity and Bigfoot are found in the real world with about the same frequency. David Wong
